A medically treated multiple cerebral hydatid cyst disease.

Echinococcosis is a potentially fatal parasitic disease that can affect many animals and humans. The disease results from infection by tapeworm larvae of the genus Echinococcus--notably, E. granulosus, E. multilocularis, E. vogeli andE. oligarthrus. Cyst hydatid disease is usually seen in adults, and mainly affects liver and/or lungs (90%). Cerebral involvement is very rare (1-3%), and more common in children. Therapy consists of medical treatment and surgical intervention if it is possible. The authors report the case of a 55-year-old male patient with multiple intracranial hydatid cysts, who was successfully treated with albendazole (10 mg/kg/day) alone without any surgical intervention.
